Top speed on ANY vehicle is governed by weight,HP,RPM @ redline & rear axle ratio.
(just because the speedo read 160mph didn't mean that the car it was installed in would go there) A 78 T/A with a 180 HP 400 & a 2:56 rear end will likely have a HIGHER top speed than a 70-74 T/A with 400 or 455 (300+HP) engine & 3:42 gears. Early 70's T/A top end suffered from a DRAG RACE drivetrain in a ROAD RACE body/chassis. 120 MPH was about all you got unless you ignored the redline.(this is why we have so many NON-numbers matching early T/A's A 5 speed or some type of overdrive would have been a GREAT HELP,but didn't materialize until our FAVORITE F-car platform(70-81) was DEAD. |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
